Overnight, the German government approved a fix that covers 1.1 million 2.0-litre EA189 turbo-diesel engines used in the Volkswagen Golf, Passat, Caddy and Tiguan, as well as the Audi A4, A5, A6 and Q5, and Seat Exeo.
This follows on from the go-ahead - given last week by the KBA - for the auto giant's proposed solution for Eos, CC and Passat models fitted with the 81kW, 100kW and 103kW variants of the 2.0-litre EA189 turbo-diesel engine.
According to both Volkswagen and the KBA, the updates will result in "no change to the fuel consumption levels, performance figures or noise emissions of the affected models".
At this stage, no fix has been approved for affected vehicles sold in the US, where diesel emission regulations are the tightest. Despite this, in late April Volkswagen and the US government agreed to a tentative settlement, which would see the car maker compensate US owners of affected diesel-engined cars.
In February, the company began recalling affected Amarok models for a software update. No further cars have yet been recalled, but yesterday Volkswagen Australia posted a video message from Michael Bartsch, its managing director, on its recall website.
"We truly appreciate everyone’s continued patience while waiting for the details of their vehicle’s update," Bartsch said in the video. "We understand that the process is taking longer than we had all hoped, but we are under way and committed to the best possible process and doing all we can to minimise any personal disruption."
